Abstract

A method for visualizing a building model comprises retrieving an identifier associated with a digital representation of a building asset from a digital representation representing at least a portion of a building, retrieving, using the identifier, a graphical representation of the asset from a building model having a different format than the digital representation, and rendering the graphical representation on a display device.

First claim

What is claimed is:

1. A method for visualizing a building model of a building, comprising:
retrieving a global identifier identifying a digital representation of a first building asset of the building, the global identifier retrieved from the digital representation of the building, wherein the digital representation of the first building asset and the digital representation of the building are both formatted as a first file format having a first file extension, the digital representation of the building comprising a graph data structure, the digital representation of the first building asset represented as a node identified by the global identifier in the graph data structure;
querying one or more databases of a plurality of graphical representations of building assets of the building model using the retrieved global identifier to identify a first graphical representation of the plurality of graphical representations corresponding to the first building asset, wherein the querying comprises ingesting the global identifier retrieved from the digital representation of the building and using the global identifier to identify the first graphical representation, the plurality of graphical representations of the building assets from the building model stored in the one or more databases are formatted as a second file format having a second file extension different from the first file format having the first file extension;
retrieving the first graphical representation of the first building asset from the one or more databases;
rendering the retrieved first graphical representation on a display device;
receiving a second building model of the building;
comparing the second building model with the digital representation of the building to identify building assets represented in both the second building model and the digital representation of the building; and
updating the second building model to include global identifiers of the building assets represented in both the second building model and the digital representation, wherein the second building model is stored as a subsequent version of the digital representation of the building.

2. The method of claim 1 , wherein the first building asset includes at least one of a space or a piece of equipment associated with a portion of the building.

3. The method of claim 1 , wherein the first graphical representation of the first building asset is associated with a simple vector format (SVF) file.

4. The method of claim 1 , wherein the building model includes a building information model (BIM).

5. The method of claim 1 , wherein the first graphical representation of the first building asset is a three-dimensional representation.

6. The method of claim 1 , wherein rendering the first graphical representation includes displaying the first graphical representation in an interface of a building management system (BMS).

7. The method of claim 1 , wherein the first graphical representation of the first building asset includes at least one image of the first building asset.

8. One or more non-transitory computer-readable storage media having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to:
retrieve a global identifier identifying a digital representation of a first building asset of a building, the global identifier retrieved from the digital representation of the building, wherein the digital representation of the first building asset and the digital representation of the building are both formatted as a first file format, the digital representation of the building comprising a graph data structure, the digital representation of the first building asset represented as a node identified by the global identifier in the graph data structure;
query one or more databases of a plurality of graphical representations of building assets of a building model of the building using the retrieved global identifier to identify a first graphical representation of the plurality of graphical representations corresponding to the first building asset, wherein the querying comprises ingesting the global identifier retrieved from the digital representation and using the global identifier to identify the first graphical representation, the plurality of graphical representations of the building assets from the building model stored in the one or more databases are formatted as a second file format different from the first file format;
retrieve the first graphical representation of the first building asset from the one or more databases;
render the retrieved first graphical representation on a display device;
receive a second building model of the building
compare the second building model with the digital representation of the building to identify building assets represented in both the second building model and the digital representation of the building; and
update the second building model to include global identifiers of the building assets represented in both the second building model and the digital representation, wherein the second building model is stored as a subsequent version of the digital representation of the building.

9. The one or more non-transitory computer-readable media of claim 8 , wherein the first building asset includes at least one of a space or a piece of equipment associated with a portion of the building.

10. The one or more non-transitory computer-readable media of claim 8 , wherein the digital representation of the first building asset and the digital representation of the building are associated with the first file format, the plurality of graphical representations of the building assets from the building model stored in the one or more databases is associated with the second file format different from the first file format, and the first graphical representation of the first building asset is associated with a simple vector format (SVF) file.

11. The one or more non-transitory computer-readable media of claim 8 , wherein the building model includes a building information model (BIM).

12. The one or more non-transitory computer-readable media of claim 8 , wherein the first graphical representation of the first building asset is a three- dimensional representation.

13. The one or more non-transitory computer-readable media of claim 8 , wherein rendering the first graphical representation includes displaying the first graphical representation in an interface of a building management system (BMS).

14. The one or more non-transitory computer-readable media of claim 8 , wherein the first graphical representation of the first building asset includes at least one image of the first building asset.

15. A system for visualizing a building model comprising a processing circuit including a processor and memory, the memory having instructions stored thereon that, when executed by the processor, cause the processing circuit to:
receive or generate a building information model (BIM) of at least a portion of a building formatted as a first file format, the BIM comprising a first representation of a first building asset and storing a global identifier representing the first building asset, the BIM comprising a graph data structure, the digital representation of the first building asset represented as a node identified by the global identifier in the graph data structure;
receive or generate a digital twin representing at least the portion of the building formatted as a second file format, the digital twin comprising a second representation of the first building asset and storing the global identifier representing the first building a
